Klassinen lukko

The unscrew mechanism is honestly genius, I switched out two bracelets on the same chain in under a minute without any fiddly clasps. The threads are smooth and catch perfectly every time, so my necklace finally sits exactly how I want it.

The unscrewing mechanism feels really sturdy and satisfying, not flimsy like some other locks I've tried. I’ve already swapped out three different chains on the same bracelet without any trouble.

Finally got a chance to use it to swap out chains on a few necklaces, and the threading is smooth enough that I don't worry about cross-threading. Only wish the lock were a tiny bit smaller for delicate pendants.
